HUGO NEWMAN, OF NEW YORK, N. Y.

EDUCATIONAL DEVICE.

Specification of Letters Patent.

Patented J 11116 a, 1912.

Application filed July 6, 1910, Serial No. 570,553. Renewed March 1, 1912. Serial No. 681,612.

To all whom it may concern Be it known that I, HUGO NEWMAN, a citizen of the United States, residing at New York, borough of Bronx, in the county of New York and State of New York, have invented certain new and useful Improvements in Educational Devices, of which the following is a specification.

This invention relates to educational devices, the object of the invent-ion being to provide an improved device of this character extremely simple in construction and operation, and therefore inexpensive to manufacture, and which is made up of two sets of shiftable, readily removable and interchangeable strips, one set superimposed upon the other, and which sets of strips are so carried and supported that the device or chart may be reversible so that both sides thereof may be used, one side as an arithmetical chart and the other side as a language chart, if preferred.

In the drawings accompanying and forming part of this specification, Figure 1 is a face view of one side of this improved chart, with several of the horizontal strips partly broken away; Fig. 2 is a detail sectional View of a part thereof, taken in line 22 Fig. 1; Fig. 3 is a perspective view of a portion of one of the vertical strips; Fig. 4 is a face view of another form of frame or support for supporting the strips; Fig. 5 is a perspective view of one corner of the frame with the end stop-board removed; and Fig. 6 is a cross sectional view of Fig. 1.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

This improved chart, in the preferred form thereof shown, comprises a suitable rectangular frame 2 made up of upright end strips 3 and 4 and bottom and top strips 5 and 6, suitably connected together and provided with suitable means for maintaining the shiftable educational strips in proper position.

In the form shown in Fig. 1 the upright end frames or strips 3 and 4 are connected by a series of horizontally extending slats 7 having located at intervals along the same headed pins 8, the spaces between the pins being substantially the width of a vertical strip. The horizontal slats are so spaced apart that the space between the pins crosswise of the frame will also be substantially the width of the strip. Carried by one of the end frame members are suitable stops 9, 'one for each horizontal strip, to limit the movement of the strips in one direction. Located crosswise of the frame is a series of rows, shown as ten in number, of shiftable strips 10, which are readily removable and interchangeable one with another, and for which purpose the strips are shown provided at one side of the frame with extension portions llvwhereby they may be readily withdrawn from one or more rows and inserted in different rows, or a plurality thereof located one upon another in superimposed position in each row. Extending vertically of the frame, and across, and therefore superimposed upon the horizontal rows of strips are a plurality of similarly formed strips 12 carrying, however, different characters from those carried by the horizontally disposed strips. In the form shown in Fig. 1 the horizontally disposed stripsare provided with numerals, while the vertically disposed strips are provided with arithmetical signs, such as plus, minus, subtraction, multiplication and division, although various characters could be used on the vertical strips as well as 011 the others. For preventing the slippage of the vertical strips some suitable means may be used. In the present instance each pair of pins at the bottom of the frame adjacent to a vertical strip is provided with some suitable elastic means, such as a rubber band, the tension of which maintains the vertical strips in position. One side of this frame may be used for numerals and arithmetical signs, while the other side of the same chart may carry strips having letters of the alphabet thereon, or other characters.

In the form shown in Fig. 41, instead of providing the chart with the headed pins the horizontal strips are carried by suitable ways formed by grooving or recessing the end members of the frame, as at 1 1, suitable upright intermediate members 15 having openings in alinement with the grooves in the end members being provided to properly support and guide the horizontal strips when the same are shifted back and forth crosswise of the frame. Similarly formed grooves or recesses are provided in the top and bottom members of the frame for the vertical strips, and to maintain these strips in position suitable spring formed members 16 are provided carried by the bottom member of the frame. In the form shown in Fig. 4: the horizontal and vertical strips, which are the same as those shown in Fig. 1, are provided with letters of the alphabet, and it will be observed that several strips in each horizontal row may be superimposed upon each other, and that several vertical strips in each vertical row may be superimposed upon each other, while one set of strips, as for instance the vertical set, is superimposed upon the horizontal set, and that each strip is readily shiftable as well as removable, so that they may be interchanged one with another, and thus by a very simple arrangement permitting a great many combinations of words and figures, while one side of either chart may be used for combinations of figures while the other side is used for combinations of letters or words, thus providing not only a reversible chart, but one in which any of the strips may not only be readily shifted to change the combination but may be readily withdrawn or removed and inserted into a different place, as occasion may require.

In practice the ten rows of horizontal strips will be provided with ten vertical columns of characters, either letters of the alphabet or figures, so that by shifting the vertical or horizontal strips, or both, a great many combinations can be provided without even the removal of any of the strips. For instance,'by an inspection of Fig. 1 it will be observed that in using the educational chart the vertical strip at the left carries the minus sign, while the intermediate vertical strip carries the plus sign, the shifting of which, however, brings into view a vertical strip therebeneath carrying the division sign, while the topmost strip at the right carries the minus sign, which by shifting downward brings into view another strip carrying the multiplication sign. Of course, it will be obvious that each strip, as shown in Fig. 3, may carry Various signs, so that by means of this chart an almost inconceivable number of combinations of figures or letters can be made with a comparatively small number of strips and by a very simple arrangement and supporting thereof, thus entirely doing away with the use of endless bands or interwoven strips or other complicated features of this character.

In both forms of the frame herein shown it will'be observed that the series of rows of horizontal and vertical strips are carried by suitable guideways, the guideways in the form shown in Fig. 1 being obtained by means of headed pins, while in the form shown in Fig. 4 they are obtained by properly recessing or grooving the end frame members and by providing intermediate guide supports. It will be observed that in the structure shown in Fig. 1, as well as in that shown in Fig. 4, the guideways constitute a means of not only properly guiding the strips, but prevent the falling forward thereof in use, and that in the structure shown in Fig. 1 the same headed pins constituting these guideways for the horizontal strip also form the guideways for the vertical strips, and that in whatever position the horizontal or vertical rows of strips may be shifted so they will always be properly guided and prevented from falling forward.

In the form shown in Fig. 4, instead of using the headed pins 9 shown in Fig. 1 to limit the shifting movement of the horizontal strips, the end of the upright frame member shown in Fig. 5 is provided with a stop-board 9 against which the inner ends of the strips contact and so limit their shifting movement.

As will be understood from the foregoing description, the strips of the several rows of each set are interchangeable with each other, and the strips of one set may be interchanged with those of another, the strips being shown all of the same width. In the present construction the vertical strips are of such length that they will project from either the top or the bottom, so that they can be manipulated from either the top or bottom of the frame, the resilient holding means holding them in any of their adjusted positions.

I claim as my invention:
